rl `his invention relates to the rmounting of shafts and has for one of its principal objects to enable theshaft to be adjusted endwise` by bodil movement thereof. Another principal object isto provide for the use of two or more series of antifriction bearings in such manner that the raceway members thereof may be adjusted relative to eachother without disturbing the endwise adjustment of the shaft. Anotherl princi the shaft tb be adjuste bodily endwise wit-hout disturbing the adjustment ofthe bearin s and, vice versa to enable the bearings to adjusted without disturbing the endwise ad v justment of the shaft. Another object is to provide for the locking of the parts in adjusted position. v

The inventlon consists in the Ishaft bearing and in the parts and combinations and ar-` rangements of parts hereinafter described and claimed. In the accompanying drawing, wherein like reference characters indicate like parts wherever they occur.

Fig. l is a longitudinal sectional view of a shaft bearing embodying my inventn; and

Fig. 2 isa similar view illustrating a modified' form of the invention.

, Fig. l illustrates the propeller shaftv 1 of a motor vehicle mounted in a housing 2 which is' part 'of an axle housing or differential c arrier of well known type. Atone end of the shaft is a bevel pinion 3 which is fixed thereon or integral therewithand arran ed to mesh with the bevel ring gear 4 of suita le differential mechanism (not shown inthe drawings). Mounted lon the' shaft 1 with itsr large end abutting against the backV of the'pinion 3 is a cone 5 or inner bearing member ofan antifriction bearing. Surrounding this cone 5 is a series of taper rollers 6that run in a conical' 4cu 7 or outer bearingmember which has' a sli 'ng fitin the inner tylindrical end of the liousing. The outer en portion of the 'shaft mem r whose large end abuts againsta suitable abutment member secured to said shaft.- Surrounding this'cone is a series'of tapery rollers 9 that cooperate with a cup 10 or outer bearing member that has a sliding fit in the outer cylindrical end ortin of the housing 2.

The interior cylin rical wall 'of said housing has screw threads 11v therein ladjacent to the bearing `cup 7 at the inner end thereof and similar screw threds 12 of the san'ie pitch l '65 adjacent to the bearing cup 10 ofthe bearing al Vobject is to enable -of' the pinion 3 with the r', .threaded r' povided with a cone 8 or'inner'bearing i at the outer end thereof, said screw threads l 11--12 being spaced apart' by an annular channel or groove 13 in the middle portion of 'the housing. On the threads 11 adjacent to the bearing cup 7 Vof the inner bearing works a threaded Vrin 14 that is provided with spaced lugs 15 t at extend into the; space between sai rings opposite said annular groove or channel. Said rmg 14 is provided with an annular rib 16 or'flange. Said ring 14 abuts against the bearing cup 7 and turning of said ring independently of the-other parts of the construction adjusts said bearing cup. `An exteriorly thread d ring 17 works on said threads-'12 at the outer end of the housing and abuts againsttheabearing cup 10. Rotation of said ring 17 independently of the other parts of the' mechanism adjusts said bearin cup 10. Said ring 17 is provided with space lugs 18 that extend into the space between the two rings opposite the channel or groove 13. Said ring 17 is interiorly threaded and mounted therein is the jexteriorly threaded end of a sleeve 19 that abutsa alnst the rib 16 on saidthreaded ring 14. aid sleeve 19 isprojzided with slots 2O adapted Vto receive a tool by means of which the sleeve may be turned.

, The housing 2 is provided with an openin 21 opposite the channel 13 or recess throng a5 A which may be inserted a` tool for. se arate rotating said sleeve 19 and said tlhreaded rings 414--17 'or'for turning any two ofthem. or all three of them together..

If the sleeve 20 and the two threaded rings 14-17 are turned as aunt the whole shaft 1 may be moved endwise to adjust the mesh gear 4. If the 14: is turn separately, the 'bearing cu of the innerbearing 1s adjusted; an if the'threaded ring 17 is turned separately the bearing, cup '10- ofthe outer `bearin is adjusted. After the pinion 3 is E leoper y ineshedwith its'gear 4 and the two aring cupsl .7J-'1Q 'properl adjusted,the 100 rs1eeve19`is turned separate yin .the outer threaded ring 17 obearagainstthe -rib16 of t e' inner thread ring 14. This movement tends to spread the tworings 14- -17 apart, '1 preventing them from turnin andlosing the proper a justment of'the arngs. The

.parts maybc further locked in positonbymeans of a locking member 22 extending between lugs of the two -rings 141-17 and into a slot of the sleeve. 1 u

In the shght modification shown in Fig- 2,l the thread ring 19 at the inner end, of the housing has a rib at itsend that is overlapped by an annular rib onthe sleeve 19.' vIn locking the parts the sleeve -19 is turned'so .Y as to tend to'ipull'the-two threaded The above described constructioneasily acl commodates the relative movement of the several parts that isrequired to adjust the two booiiiigo iodio look iiiom in position. Maio .5

. same time it permits the unitary movement of all th parts that isA required to adjust the mesh of the inion with its gear. At the same. timethe locm' g of. the adjusting embersis effected without any circumferentia stress on invention' according' ly I do not wish to be limited to the detai of construction shown zov . the bearing members that would tend to impair the true circularit thereof. Obviously alls or cylindrical ro 1ers mightbe substituted for the taper rollers and other` changes might be made :without departing from the portion enga g the other ring.
